AW: [aspectj-users] What does "no suitable guard" mean?

["Moritz Post" <moritzpost@xxxxxx>]

Hallo

Thanks for the explanation. I will read into it further.
On my ajdt installation the compiler flag for the guard was warning per
default. Eclipse 3.2M6 with the appropriate ajdt.

Btw... Why isn't the ajdt able to import necessary classes when they are
declared in a aspectj5 annotation style? Or manage them via "organize
imports".
